DENNIS ALMON HOYT, OF ST. CLOUD, MINNESOTA.

LAWN-SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 440,159, dated November11, 1890.

Application filed July 30, 1890.

To all whom it may concern:

Be it known that I, DENNIS ALMON HOYT, a citizen of the United States,residing at St. Cloud, in the county of Stearns and State ofMinnesota,have invented certain new and use ful Improvements inLawn-Sprinklers; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to'which it appertains to make and use thesame.

My invention relates to a sprinkler adapted to various situations, butspecially designed as a lawn-sprinkler.

The invention consists in the construction and arrangement hereinafterset forth in the description, and pointed out in the claims.

The same letters refer to like parts in the several figures of thedrawings, in which- Figure 1 represents a side elevation of my sprinkleras it is applied in actual use. Fig. 2 is a vertical section of thesprinkler-head and portions of the adjoining parts. Fig. 3 is a top viewof the deflector or shield before being bent.

A suitable tubeA is mounted in a vertical position upon any suitablesupport, but preferably upon a pointed foot, which enables it to beforced into the ground. The main tube A is connected to my sprinkler bymeans of screw-threads arranged therein, or otherwise,

which latter is composed of two parts B and C. I prefer to construct thepart B of hemispherical form, with its mouth directed upward and havingcast therewith a bar or step F, for a purpose hereinafter to bedescribed. The part 0 is similar in construction to the part B, exceptthat its mouth is turned downward, and it is made adjustable to and fromthe part B by some appropriate mechanism, such as that shown in thedrawings, and which will be now described.

I mount a vertical rod E on the bar or step F and project such rodoutward and through an aperture formed in the top of the part 0, thelatter being fastened thereon by means of a collar G, arranged toencircle the rod and adjustable thereon by means of a set-screw a, as isshown. Arranged upon the same rod is a shield or deflector D, which inthis instanceis shown as consisting of a metallic, preferably tin, pieceextending downward and fierial No. 360,377. (No model.)

beyond the apertures 12, arranged for the exit of the water from thesprinkler-head. This metallic piece D is conveniently formed of aflaring or bell shape, and is out into a number of strips with the slitsgradually widening as they extend to the end of the flaring deflector.In Fig. 3 the deflector D is shown as cut from a sheet of tin beforebeing bent, as shown in Fig. 2.

I have described the preferred form of my invention; but it is obviousthat many modifications might readily be made in the several featuresthereof, which would be within the skill of a mechanic and would notdepart from the spirit or principle of myinvention.

I have found that the construction shown and described is botheconomical and efficient, and also is very simple and therefore easy tomanipulate.

The operation is as follows: Water is conducted by any convenient systemof tubing .to the pipe or tube A, and thence to the sprinkler-head,fro1nwhich it is forced through the openings b and is directed against thedeflector or shield D, by which it is broken and caused to be wellscattered and distributed. The openings 1) are formed by the space leftbetween the hemispherical heads B and C, and they may consist of acontinuous space of the same thickness or otherwise, as is usual. Thesize of the openings, and consequently the amount of water issuingtherefrom, is regulated by the adjustment of the upperhemispherical-part G of the sprinkler-head upon the rod E by means ofthe collar G and the set-screw a.

What I claim, and desire to secure by Letters Patent, is

1. A sprinkler comprising two hemispherical portions with a spacebetween their adjacent edges, the one portion adjustable with referenceto the other portion and a flaring deflector on the outside of suchportion and arranged to extend over the apertures formed by the spacesbetween said portions, substantially as and for the purpose set forth.

2. A sprinkler comprising two hemispher ical portions with a spacebetween their adjacent edges and a deflector surrounding such portionsand composed of a single piece of metal formed into a series of strips,substantially as and for the purpose set forth.

3. A sprinkler comprising two hemispherical portions, one having a stepin which is secured a rod and theother a collar and setscrew foradjusting the same upon said rod, and a flaring deflector arranged toinclose said portions and carried by the rod and upper hemisphericalportion, substantially as and for the purpose set forth.

4. A lawn-sprinkler comprising a suitable stand, pipes communicatingwith the sprinkler-head composed of two hemispherical portions having aspace between their adjacent edges and adjustable with reference to eachother, and an outer flaring deflector formed of a single piece of metalcut into a series of 15 strips, substantially as and for the purpose setforth.
